Syntypes. MCZ-IZ 9001: Trinidad and Tobago, Trinidad, “Maguaripe Bay” (=Macqueripe Bay), 24 July 1937, several colonies or colony fragments, up to 23 mm high, in good condition, without gonophores, together with several other hydroid species, coll.

MCZ-IZ 9128: Trinidad and Tobago, Trinidad, “Maguarepe Bay” (=Macqueripe Bay), 24 July 1937, several colonies or colony fragments, up to 13 mm high, in fair to good condition, without gonophores, together with at least 14 other hydroid species, coll. E. Deichmann; formalin to 80% ethanol (currently shelved under Diphasia tropica ).

Lectotype, by present designation. (MCZ-IZ 9001): Trinidad and Tobago, Trinidad, “Maguaripe Bay” (=Macqueripe Bay), 24 July 1937, one colony, 23 mm high, in good condition, without gonophores, coll. E. Deichmann, labelled “ type ” and “ holotype ”; 70% ethanol.

Paralectotypes. MCZ-IZ 146029: Trinidad and Tobago, Trinidad, “Maguaripe Bay” (=Macqueripe Bay), 24 July 1937, several colonies or colony fragments, up to 15 mm high, in good condition, without gonophores, together with several other hydroid species, coll. E. Deichmann; 70% ethanol.

MCZ-IZ 9128: Trinidad and Tobago, Trinidad, “Maguarepe Bay” (=Macqueripe Bay), 24 July 1937, several colonies or colony fragments, up to 13 mm high, in fair to good condition, without gonophores, together with at least 14 hydroid species, coll. E. Deichmann; formalin to 80% ethanol.

Type locality. Trinidad and Tobago: Trinidad, “Maguaripe Bay” (=Macqueripe Bay) ( Fraser 1943a).

Current status. Invalid.

Remarks. Fraser (1943a: 81) described Aglaophenia insolens from “numerous colonies” in a collection sent to him from the MCZ, but no types were designated for it in the original account. Two lots assigned to the species exist at the MCZ, with one of them (MCZ-IZ 9001) indicated as type material in the current online database. That collection includes several colonies or colony fragments. The second (MCZ-IZ 9128) is part of the same collection from Trinidad, and is regarded here as syntype material as well (ICZN Art. 72.1.1; 72.4.7). No other type material is known to exist.

Of the available syntypes, the largest colony from the collection labelled “ type ” (MCZ-IZ 9001) is selected as the lectotype (MCZ-IZ 9001). Measuring 23 mm high, and in good condition, it is likely the specimen referred to by Fraser in the original description (“…the largest colony observed was 24 mm ”). The remaining colonies of the species from that collection (MCZ-IZ 146029), as well as those in the other (MCZ-IZ 9128), are paralectotypes.

Aglaophenia insolens , reported only from the type locality, has been regarded as conspecific with A. rhynchocarpa Allman, 1877 ( Calder 1997; Galea 2013). Synonymy of the two is currently upheld in WoRMS. Bogle (1975: 67) had earlier assigned A. insolens to the synonymy of A. rathbuni Nutting, 1900 , a species she suspected was “…merely a variant of A. rhynchocarpa ”.
